To all whom it may concern:

Be it known that I, Wrmmmf JOHANNES LORENZ BAUER, citizen of the'Republic of Germany, residing at Frankfort-on-the- Y 5 Main, in the county of Hessen-Na'ssau and State of Prussia, have invented a new and useful Improvement in Collecting Electrodes for Electrical Gas-Cleaning. Apparatus, of which-the following is a'specifi- I tlcal manner the production of strains with-- 1n the plates. The.slots 2 also facilitate the 1 cation. V

The present-invention relates to an improvement in collecting electrodes for 'elec-.' t'rieal gas cleaning apparatus, and part1cu-' larly to electrodes for this purpose which are formed of carbon bearing material. It has been found that such electrodes are es pecially resistant at hightemperatures and for treatment of corrosive.

According to the present collecting electrodes may be formed of ma terial such as has been used for the'production of the carbon. electrodes for electri- I "trlcal precipltators comprising a molded cal fuignaces. These carbon electrodes are formed in any suitable shape for example as plates and may be more or less carbonized according to the electrical resistance and the chemical resistance desiredj One' way in which the, lates or electrodes may be formed is by mo lding a mixture ofsuitable carbonaceous binding material (for example tar or'piteh) with a poorly conducting material (semi-conductor or non-conductor) such for example as chamotte (a mixthe mixture being molded to desired shape and then burnt so as to harden the clay electrodes y r According to this-invention the .collect-' ing electrodes may "also be formed oftwo 45 or more plates attached to or in contact with.

one another, 'said plates being, if desired, of difierent conductivity'and composition,

- subscribed my forming composite electrodes.

, An embodiment of the invention is 11 trated inthe drawing, showing a collecting electrode constructed according to the invention.

As shownthe collectiilg electrode consists of several individual plates .1, for example,

gases or material that are invention the ture of fire clay with broken fire brick)' with the carbonaceous material to form the of carbonizedelectrode bodiesysuch as are to-and-fro movement of scraping devices in .case same are used to cleanthe electrodes.

The slots serve to guide such scraping devices by engagement with suitable parts of such devices. D

What I claim is: i 1. A collecting electrode for an electrical gas cleanin apparatus comprising an electrode member consisting throughout of a mixture of --semi-conducting non-metallic material and carbon.

2.- 'A collecting electrode member for elecplate-shaped body consisting throughout of a mixture of semi-conducting"nonemetallic material and carbon; Y

3. A collecting electrode member for an electrical gas cleaning apparatus consisting wholly of a body of semi-conducting mate rial mixed with carbon.

4. A collecting electrode member for an electrical gas cleaning apparatus consisting wholly of a body of burnt clay-containing material mixed with carbon.

A collecting electrode member for an electrical gas cleaning apparatus consisting wholly of a mixture of burnt clay-containing material and carbonized-j carbonaceous material.

65A collecting electrode for an electrical gas cleanmg apparatus consisting of a plurality of individual plates each consisting of semi-conductingmaterial and-said plates having their adjacent edges 'recessedto form .slots. a J c y In testimony. whereof I have hereunto ber, 1923.
